FASTENING DEVICE.

Specification of Letters Patent.

Patented Apr. 29, M919.

Application filed February 25,1918. Serial No 219,099.

To all whom it may concern:

Be it known that I, WILLIAM H. Been, a citizen of the United States, residing at Chicago, county of Cook, andState of Illinois, have invented new and useful Improvements in Fastening Devices, of which the following is a specification.

My invention relates to a fastening device intended more particularly for securing in place the sashes of glazed steel partitions now in extensive use in large manufacturing and mercantile buildings in such manner that the sashes may be removed and replaced in taking down and reerecting the partitions without breaking the putty or in any manner disturbing the glazing. The object of my invention is the provision of a fastener capable of such use, and which shall be con-- venient, sightly, and well adapted for the purposes for which it was designed. My invention consists in the construction of such a device with and its application to a glazed sash and its supporting partition, and in the construction, formation and arrangement of the device itself, as illustrated in the accompanying drawing and hereinafter described, the essential elements of my invention being more particularly pointed out in the appended claims.

Of'the drawings Figure 1 shows a front view of part of a glazed partition to which my invention is applied; Fig. 2 is an enlarged horizontal section through a pair of fasteners and adjacent parts of two glazed sashes and an interposed mullion of the partition structure as indicated by the line 2-2 of Fig. 1; Fig. 3- is a perspective view of a fastener member applied to a fragment of a sash, part of the putty being broken away; Fig. 4 is a horizontal section corresponding to Fig. 2 but showing a modified form of fastener; and Fig. 5 is a horizontal section of a different modification, taken centrally of the block.

In a typical partition of the class for which my invention is particularly designed, the partition units (which individually may be made up wholly of glazed sash members, or may include swinging or sliding doors) are adapted to be framed between vertical mullions 1, suitably secured at their bottom and suitably secured to the ceiling at their top, or connected by an impost member to form a secure partition frame. Usually the lower portion of the partition consists of sections known as kick plates (indicated by the reference numeral 2) secured between the mullions, above which are arranged the glass sash members or partition units to which my invention particularly relates.

Describing now the particular structure and embodiment of my invention illustrated in Figs. 1 to 3, the sash frame consists of outer vertical and horizontal L-shaped bars 3 connected by T-shapedmuntins 1 to form seat for the panes of glass 5. The fastener 6 is arranged in theangle between the glass 5 and the marginal flange 3 of the sash frame, its outer face is beveled or inclined to lie flush with the surface of the putty A, which is applied in the usual manner. Preferably the fastener is formed with orificed lugs 13 engaged by screws 14 which secure it to the flange 3, although such lugs may be omitted from this form of fastener, if preferred. Centrally the fastener is formed with an external recess 8 to receive the slotted head of a bolt 9, the other threaded end of which is adapted to-engage a nut 10 arranged in the recess of a similar fastener member 6? on the opposite side of the mullion 1, as' shown in Fig. 2, one of the fiat side faces of the nut cooperating with the rear wall of the recess to prevent rotation of the nut when the bolt is I turned. However, it will be-understood that at the ends or corners of a partition, a shorter bolt or screw screwing directly into the adjacent frame member of the partition may be used in connection. with a single fastener.

In Fig. 4 I have illustrated a modified form of fastener, indicated by the numeral 11, similar in construction to that already described, but in which the central recess extends as an opening or orifice 12 entirely through the fastener so that the head of the bolt 9 seats directly on the flange 3 of the sash frame. In this form of fastener, however, it is desirable that the orificed lugs 13 above mentioned by which the fastener is secured to the flange 3 shall not be omitted. Where it is desired to secure two sash members in place on opposite sides of a mullion, as shown, the screw-threaded end of the bolt 9 is arranged to engage a nut disposed within the orifice of a similar fastener 11" secured to the sash frame memher 3 of the second sash frame.

If desired, a solid fastener block 15, such as shown in Fig. 5 may be used in connection-Witha bolt andeither such a fastener V as shown in Fig. 2, or a fastener-such as that shown in Fig. 4. It is obvious, further, that this form of fastener block may be provided with lugs corresponding to the lugs 13 of "the fastener shown in Fig. 3 in order to securely holdthe. fastener-in place regardless of its adhesion to the putty or the engagement of a fastening bolt.

I claim:

1. a In stnucturesof-the character described and including apartition frameand a sash frame :having ,marginal outStanding flanges and a glass seated within such flangesand a beveled:retainingavall of ,putty within the angle between the glass and flanges, a chambered fastener-interposed inthe putty wall .and extendingtherethrough, and abolt having .-itshead seated insaid chambered fastener' and arranged to clamp saidsash frame to said partition frame.

In structures of the character described and including a partition frame and a sash frame. having marginal. outstanding flanges and a glass seated Withinsuch-flanges and a beveled retaining wall of putty within the angle between the glass and flanges, a'chambered-fastener interposed inthe aputty wall and having an orificed bottom adapted to engage the head of a bolt and a beveled top lying flush with the surface of the putty wall, said fastener being formed wvithlugs and such lugs being secured to the/flange of the sash, and a bolt having its head seated in said chambered fastener, and arranged to clamp said sash" frame to said partition frame.

5. In structures of the character described, a chambered fastener accordingto claim 1 in which the chamber is adapted-to receive the nut of the fastening 'bolt,=, whereby said fastener may be used in pairs on opposite sides of an interposedmullion.

G. In structuresof the character described, a pair of chambered fasteners-according to claim 5 in which an interior wall. of the chamber and the nut are formed to cooperate to prevent rotation of the nut and the fastener having such chamber is secured to the adjacent sash flange.
